When you look at the circulation you can see the blood is flowing. This is caused by microsaccades or Eye moment, and the tiny moving thing is believed are after images of the black and white lines.

Just keep looking at those 3 spot over the nose for 10 sec. Then raise you head to the roof or a blank wall and keep looking for 20 seconds. Share what you see with us.

Gaze at the black square, you will perceive the red flower reverses after stopping. However when looking at the red flower directly it does not reverse.

Explanation: The flower reverses after stopping because it’s last images still exist in our brain, actually it is “afterimage effect” and plus with peripheral visual system.

In this illusion, there are two motions:
1. the blue rectangle moves in straight way
2. the background with black and white color rotates in one direction

If you look directly at the blue rectangle, you will perceive it move straight and does not change its color. When you look at the red square, you will perceive it moves in a zigzag way (the direction of the rectangle depends on the current rotation angle of the background) and its color changed brighter when moving in black areas and darker when moving in Grey areas.

The motion of the rectangle and the background create two sources of information.
when we look at the display, we can discern multiple features simultaneously but its quite different when we look at the display peripherally. It is hard for our visual system to analyze sources of information exactly.

The motion of the background is global motion and the motion of the blue rectangle is internal motion. It could be the global motion affects to the internal motion because the global motion has a stronger affection than the internal motion to the peripheral visual system.

There are many illusions only work or work better in peripheral visual system (e.g: lightness illusion, color illusion, contrast illusion, image aftereffect)

In this illusion, the blue rectangle’s color changes is kind of lightness illusion but it only works in peripheral visual system. Sometimes, we are in “passive peripheral visual system”, for example when we look at a moving picture but when we really concentrate look at a point in the picture then whole picture will stop moving.
